DOUBLE-BEADED THREE-WAY SIGNAL LIGHT.

Application tiled July 9, 1993. Serial` `No. 650,567..

'lhis invention relates to. a signal and particularly to means indicating the direction of travel of automobiles or the like.

jitn important object of the invention is to provide a signal of this `character which is simple in construction, durable, and can be manufactured at a comparatively low cost.

l further object of theinvention is the provision of a signal which can be seen from the front or rear of the vehicle upon which it is inounted and also opeiate as a stop light.

Il. still further object of the invention is the provision of a signal of this character which can be readily seen for comparatively long distances without providing an unduly large structure.

@ther objects and advantages of this invention will be apparent during the course of the following description.

ln the accompanying drawings forining a part of this specification and in which like numerals are employed to designate like parts throughout the sanie:

Figur? l is a perspective view of iny iini proved device,

liligure 2 is a cross section taken therethrough,

litigare 3 is a horizontal section taken on line 33 of litigare 2,

Figure Ll is a perspective view of the light shield, and p Figure 5 is a perspective view ot a portion of the casing arranged within the device.

ln the drawings, wherein for the purpose of illustration is shown the preferred enibodinient of iny invention, the numeral l() generally indicates the outer casing of iny improved signal, this casing being substantially oval shape in cross section and constructed of comparatively thin yet durable nietal. i rl`he casing is closed at each end by a plate 1l, each having an indicia opening in the shape of a double headed arrow, the heads being designated by the numeral 1Q and the connecting stem by the numeral 13.

Mounted in the oval shaped casing l() is a substantially Ll-shaped frame 14, which ex tends-between the opposite end plates 11 and i4 is provided with a cover 15 engaging over the upper edges of the opposite side portions of said U-shaped frame, forming an inner casing. Mounted on the bight or connecting portion 'of the U-shaped frame 14 approximately at the center thereof is an angle member 16, to .the opposite ends of which are attached electric light sockets i7 for receiving electric bulbs 18. lt will be noted by referring to Figures 2 and 8 that the electric light bulbs are arranged approximately midway of the length of the U-shaped structure and slightly spaced inwardly from the'opposite side portions thereof. It is also to be noted that the lights are arranged in alignment with said arrowheads of the indicia openings in the end walls of the casing. the purpose of which will be set forth as the description proceeds. v

` Arranged within the inner casing formed by the U-shaped frame lll and cover l5 is a substantially inverted lJ-shaped frame 19, which also extends to both end plates 1l of the easing. rllie opposite side portions of the inverted U-shaped frame 19 are in alignment with 4the electric light bulbs 18 respectively and the inner ends of the arrowheads with the stem of the double headed arrow-shaped in dicia extending between said side portions of the frame. The said side portions of the inverted U-shaped frame forni partitions and are split intermediate their ends to provide oii'set portions or shields .20 extending inwardly of said partitions and downwardly, as clearly shown in Figures 2 and lof the drawings. By stamping out the partitions to form the shields it provides for locating the electric light bulbs in alignment with the opposite end portions of said portions, the. shields extending downwardly at angles between the electric light bulbs to prevent light rays from one bulb being reflected through the small opening provided for receiving the other bulb, as clearly shown in Figures 2 and 3 of the oiiicial drawings.

The shield 20 adjacent the lainp that is lighted will act as a shield and prevent light rays from shining through the small opening in the opposite partition or side portion of the inverted U-sliaped structure which receives the other bulb, and likewise the opposite partition of the inverted ll-shaped frame will prevent light rays from passing through the arrowhead opening at the opposite side of the casing from the lighted electric lainp. It will be clear therefore that when either lamp is lighted itwill not only light the arrowheads on a line therewith at opposite ends of the casing 1() but will also lig t the stem for its d entire length, as indicated in Fig.r` 3, the op*- therewith partition 19 and shield 20 cooperating preventing the light from shining through the opposite arrowheads. In this manner an arrow pointing in either direction at both ends of the easing can be shown according to direction to be indicated by lighting one of the lamps, and the double headed arrows shown by lighting both lamps,

It is to be understood that the form ot' my invention herein shown and described is to be taken as the preferred example of the same, and that various changes as to the shape, size, and arrangement of parts may be resorted to, without departing from the 'spirit of the invention, or the scope of the subjoined claim.

Any approved means may be employed for holding the glass plates 11 at the ends ot the outer easing in place, as for instance a flanged ring 25 at each end of the casing secured to the sides of the latter by screws QG. said rings clamping the glass plates against the ends et the casing as shown in the drawings.

posite Having thus described my invention, what I claim as new is:

A direction signal device for automobiles comprising a casmg having indicia openings in its opposite ends, each opening being in the Shape of a double headed arrow, an inner casing of approximately the saine size as the indiela openings in the ends of the casing and cooperating with said ends, spaced apart partitions extending between the ends of the casing in alignment with the inner ends of the arrowheads, respectively, and having intermediate openings through the same, shields spaced from said openings `at the inner sides thereof, and electric lamps located in the openings in the partitions whereby light from either lamp will be projected at opposite sides of the partition in which the lamp is located and through the opposite arrowheads at one sidel of said partition as well as the stem at the other side of the partition.

WILLIAM HENRY WETZEL.
